What Is The Freezing Point Of A Solution That Contains 123 G Of Ethylene Glycol And 150 G Of Water?

From Chemistry Forum:

What is the freezing point of a solution that contains 123 g of ethylene glycol and 150 g of water? What is the freezing point of a solution that contains 123 g of ethylene glycol (C2H6O2) and 150 g of water? Please help and if you could show each step. Thanks

Answer: Molar mass of CHOU is 62.0 g / Mil so we have 123 / 62 Mil of glycol = 1.984 moles these are in 150 g OD water so moles per kg of water = 1.984 x 1000 / 150 = 13.227 moles molality of the solution is 13.227 mole /kg of water delta t = m x Kg = 13.227 x 1.86 = 24.6 oC freezing point is -24.6oC

What Mass Of Helium Gas Is Needed To Pressurize A 123.0 L Tank To 243 ATM At 25°C?

From Chemistry Forum:

What mass of helium gas is needed to pressurize a 123.0 L tank to 243 ATM at 25°C? What mass of helium gas is needed to pressurize a 123.0 L tank to 243 ATM at 25°C? What mass of oxygen gas would be needed to pressurize a similar tank to the same specifications?

Answer: PVC = nRT P is pressure in atm V is volume in L n is moles R is the gas constant (we'll use .0821 L atm/mol K) T is temperature in K convert C to K: 25 C + 273 = 298 K plug in and solve for n: 243 ATM (123 L) = n (.0821 L atm/mol K) (298 K) 1221.66 Mil = n use molar mass of helium gas (4 g/mol) to convert Mil to g: 1221.66 Mil * 4 g/mol = 4886.66 g He when finding the mass of oxygen gas, the moles are the same; simply use the molar mass of oxygen gas (remember O gas is diatomic, so the molar mass is 32 g/mol): 1221.66 Mil * 32 g/mol = 39093.12 g O2

What Is The Meaning Of 123 In Nuclear Agreement Between America And India?

From Politics Forum:

What is the meaning of 123 in nuclear agreement between America and India? Recent agreement between India and America for nuclear deal is called one, two, three agreement? What is the mean of 123?

Answer: It refers to Section 123 of the Atomic Energy Act of 1954. An agreement for nuclear cooperation made between the U.S. and another country following the provisions of this section is called a 123 agreement. Section 123 says that the United States can't enter into an agreement for nuclear cooperation with another country unless certain criteria are met. For example, the other country has to have agreement in place with the International Atomic Energy Agency to safeguard nuclear material, equipment, and technology so that it won't be diverted for weapons use. In this case, since India has nuclear weapons, Congress had to authorize the president to waive certain requirements of section 123.

From Football (American) Forum:

Are Yahoo users Elk and 123 going to have a feud when the Browns and Lions play later this season? Elk is a die hard Browns fan And 123 is a die hard Lions fan. God Bless them both. I feel really bad. So bad that I want the Browns and Lions to win at least 3 games this year. All they have to do is when 2 more games each plus they play each other. I think these teams will be really good years from now. It's a matter of time.

Answer: I think both ELK and 123 are looking forward to that game. I'm sure they both believe they have a chance of winning. I'll say one thing, the questions before and after will be extremely entertaining. It makes me look forward to the pregame and post. Seriously...it does and we're talking Browns and Lions! Both are true examples of optimists, and their humor is awesome.

Why Do Number Keypads Sometime Start With 123 At The Bottom And Sometimes At The Top?

From Other - Hardware Forum:

Why do number keypads sometime start with 123 at the bottom and sometimes at the top? My desktop number keypad starts with 123 at the bottom, my cell starts with 123 at the top. why aren't they uniform, like QWERTY keyboards?

Answer: Cell phone keypads layouts mimic TouchTone(tm) telephone keypads. That design goes back to the 1960's, or so. Computer numeric keypads mimic adding machine layouts. They go back even further... Why didn't Ma Bell mimic adding machine layouts when designing the Touch Tone layout? That's a good question.

How To Find The Natural Abundance Of Antimony 121 And 123?

From Chemistry Forum:

How to find the natural abundance of antimony 121 and 123? You are given the mass of antimony 121 as 120.904 and 123 as 122.904 and we are supposed to find the natural abundance percentage by using the periodic table value of antimony(121.760)

Answer: The value on the periodic table is the abundance of each mass multiplied by that mass. So figuring that there has to be a total of 100% abundance, you have x% of one, and 100%-x% of the other. Your equation is then %A*m1 + (1-%B)*m2 = Mass on table A*120.904 + (1-A)*122.904 = 121.76 120.904A + 122.904 - 122.904A = 121.76 -2A = -1.144 A = 0.572 So Sb has 57.2% abundance, Sb has (1-0.572) = 0.428 = 42.8% abundance

Pelham 123 Why Is The Original A Classic Of Its Genre And The New Version Is Not?

From Movies Forum:

Pelham 123 why is the original a classic of its genre and the new version is not? I've just watched both versions of Elohim 123 and the original (1974) is far superior. But why? Is it the script, the actors, the direction. The original is grittier and more realistic whereas the new version is slick and fun but lacking something. What is it lacking? Interested to hear your comments. Yes, the ending is a cracker! The original is believable.

Answer: The original had a sense of humor, thanks in large part to Walter Martha and Jerry Stiller. It also had Robert Shaw who was perfect as the villain. There was no back story to their characters, like in the remake. There was also no psychobabble between Martha and Shaw like there was with Densely Washington and John Travolta. Travolta's character was so over the top that it was just silly to me. The original also had a better ending, when Martha catches Martin Balsam.
